Well he said Cybertech is obsolete.
Oh, right, man I'm thinking modulators, not modifiers. Yeah I know every crew skills gets to make that stuff.
Cybertech is no more obsolete than any other crafting skill (they're not).
All crafting skills make mods. All crafting skills can make Epic mods through enough Reverse Engineering (RE crafted green mods until you learn blue, RE blue until you learn Purple/Epic).
Whether those are of the same or lesser quality as raid dropped mods remains to be seen (odds are raid dropped mods will be higher quality - but it's not really any different than WoW's periodic raid-only gems).
If I remember correctly, the current mod slot types are:
Triggers (unique to guns)
Hilts (unique to lightsabers)
Armoring (unique to armor)
Modification
Enhancement
I haven't seen any critical crafting successes, and thus no "Modulator" slots in the last two builds, but I wasn't concentrating on crafting as much as I did earlier due to all the frequent wipes.
